Section 1: Introduction

1.1 Component Identication

Ethernet: A technology for high-speed bandwidth connectivity over local area networks (LAN).

Client Radio: This radio receives

signal from the server radio. The client radio is connected to and receives power from the display. Signal between the client and the display is both transmitted and received.

Server Radio: This radio is connected to the local Ethernet network through a DC injector which provides power to the radio. It transmits and receives information to and from the client radio at the display.

DC Injector: This unit, shown in Figure 5, receives signal in from the

customer’s network and relays signal out to the radio. It contains a power input to power the server radio.

Figure 1: Ethernet Bridge Radios – Two-Wire Client Radio

Note: The DC Injector is for indoor use only.

Optional USB to Ethernet Adapter:

This bypasses complex network configuration in situations where simple point-to-point communication is required. The adapter creates a secondary network, which is dedicated for communication with a Daktronics Galaxy® display. Normal network operation is still enabled through the primary network.

Introduction 1

Section 2: Installation

The controller has either a default IP address (172.16.192.25) for Galaxy® displays or a DHCP address for GalaxyPro® Series displays. Once the default IP address is used to connect to the display, it can be changed to a personalized address. Refer to the display manual for further information on setting an IP address. Various LAN and Internet service providers (ISP) have differing IP requirements. Consult the network administrator or ISP for more information. The DHCP address automatically adjusts to suit the local network.

2.1 System/Cable Requirements

In an Ethernet radio system, two radios are required. A server radio transmits/receives signal to/from a client radio, shown in Figure 1 and Figure 2, at the display. The server radio connects to the Ethernet LAN through a DC injector.

Daktronics provides a yellow 20-foot CAT 5e Ethernet cable, which is required to connect the DC injector to the LAN. The customer must supply a longer cable if it is needed.

Ethernet and power cables are provided to connect the client radio to the display and the server radio to the DC injector.

A Windows®-based computer is required (but not provided) to run Venus® 1500 control software.

An Ethernet radio-controlled display requires the following connections, refer to Figure 3 for a system layout:

pointing upward. Figure 4 illustrates correct and incorrect antenna placement.

Do not mount the radios with the wire grommet pointing upward.

There are two types of client radio connectors for Galaxy products – two wire – Figure 1 and single wire – Figure 2.

1. A CAT 5e Ethernet cable is routed from the LAN switch/

router to the DC injector.

Note: The DC Injector is for indoor use only.

2. The Ethernet cable connects to the Switch Hub jack on

the DC injector, as shown in Figure 5.

3. The DC injector is provided with an AC power adapter.

The AC power adapter is connected to the AC input jack on the DC Injector and inserted into a 120 VAC wall outlet.

4. The server radio is provided with a 25 ft.

(7.6 m) attached Ethernet cable. This Ethernet cable is connected to the RJ45 jack on the DC injector.

The maximum distance between the

network switch and server radio is 300 ft. (91.44 m). Note: Install a Cat 5e inline coupler, example shown in Figure 6, to the end of the server radio cable and connect it to a high-quality Cat 5e cable.

Figure 4: Antenna Alignment Examples

Figure 5: DC Injector

5. Mount the server radio outdoors for best signal

quality. Indoor mounting significantly reduces signal quality and can cause communication issues to the display.

6. Mount the client radio within 25 ft. (7.6 m) of the

input jacks.

7. Route the signal quick-connect cables from the

enclosure to the rear of the display.

The cable from the enclosure to the display can be routed through conduit or through the display pole, and should be secured to protect it from weather or vandalism. Provide drip loops to prevent water migration to display quick-connect interface board.

8. Connect the quick-connect cables to the top two (J32

and J33) jacks. Refer to Figure 7 and Figure 8 for examples. Or connect the quick-connect cable to the middle jack if the display is a single-cable design, as shown in Figure 9 and Figure 10.

Troubleshooting and Radio Diagnostics 7

If a disconnect state is noted on the Network Map, check how the radios are installed. Are they installed correctly with both antennas pointing upward and are the radios mounted high enough to eliminate obstructions like semi-trailer traffic? Or are there

Signal Strength Bars

obstructions like trees between radio installations? Are the radios installed at an appropriate distance to one another?

All of these can disrupt signal strength. If the radios are installed correctly, but transmission problems still exist, call the Daktronics Help Desk at 866-343-3122 for further instruction.

Observe the diagrams that represent the Server and Client radios.

Figure 16: Server and Client

The bars reflect Signal Strength and are directly affected by the Block Error Rate
